Covestro begins supply world´s first climate-neutral polycarbonate

January 3, 2022 |

In Germany, materials manufacturer Covestro has started supplying the world´s first climate-neutral polycarbonate from its Uerdingen site in Germany, delivering on its promise to introduce these products by the end of 2021. These Makrolon polycarbonate grades are climate-neutral from cradle to gate, thanks to the usage of renewable electricity for Covestro production processes and the introduction of raw materials coming from mass-balanced bio-waste and residues.

The company is gradually converting to alternative raw material sources including renewables as part of a comprehensive program to drive forward the transition to a circular economy. Integral to this program is the adoption of the mass balance approach, which is a chain of custody method that allows fossil and alternative feedstock to be mixed in production but separated in bookkeeping. It is able to track materials through the value chains and allows attribution of alternative feedstock, like bio-based raw materials, to selected end products.

Through the mass balance approach, alternative raw materials are introduced into the value chain while taking advantage of the existing chemical infrastructure with its high efficiency and economies of scale, accelerating the transition of the industry to a circular economy of plastics.
